8 month owner here, let me supplement the review a bit.
I've been using this board since Haswell was released. Its running my 4770K at 4.5GHz and the memory is at 2400MHz. You forgot to mention the single reason this board is worth purchasing over the ASUS competitor. There was a 3 month...
The only time I read about a similar problem with the pure DP connector, the guy said he fixed it by replugging the connector. He said his cord didnt easily lock snugly in the socket.
